If you want to try using a Linux terminal and are not sitting anywhere near a Linux system, don’t worry. There are some services that allow you to run a Linux terminal inside a browser. This post examines some of these and should give you a sense of what you can do and the performance you might encounter.
All Linux Terminal sessions described here ran on Windows using the Chrome browser. While you can easily run a Linux terminal in a browser on Linux, you will likely be less motivated to do so.
You will find the links available for JSLinux through this site:
Of the eight systems listed, there are six Linux systems. Go to one of the listed console windows. These URLs include:
I prefer Fedora 33 from JSLinux because it includes human pages while the other two don’t seem to.
You will end up logging in as root, even though the . file World Health Organization It won’t be up to you to acknowledge your existence. However, the who am I and the pwd The command will confirm your identity:
localhost:~# who; whoami; pwd sh: who: not found root /root
If you wish, you can collect files hi c program and run it, you should see this.
localhost:~# cc -o hello hello.c localhost:~# ls
bench.py hello hello.js hello.c readme.txt localhost:~# hello sh: hello: not found localhost:~# ./hello hello world
You may want to run some of your favorite Linux commands, put a text or two together and explore the command line. I compiled and ran a simple bash script to count the number of files in each directory in my search path.
$ cat count_commands #!/bin/bash for dir in `echo $PATH | sed “s,:, ,g”` do echo $dir ls $dir | wc -l echo “==========” done
[root@localhost ~]# ./count_commands /usr/local/sbin 0 =========== /bin 2349 =========== /sbin 609 =========== /usr/bin 2349 =========== /usr/sbin 609 =========== /usr/local/bin 9
It is clear that the system is equipped with many Linux commands.
If you run into problems when trying to run a script, source the script like this:
[root@localhost ~]# ./count_commands sh: ./count_commands: not found [root@localhost ~]# . count_commands
Even with the current file system location in my search path on one of the systems, I needed the source script to run.
To check your search path, use a command like this:
$ echo $PATH /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
The man page directories in Fedora look like this:
[root@localhost ~]# ls /usr/local/share/man man1 man2 man3 man4 man5 man6 man7 man8 man9 mann man1x man2x man3x man4x man5x man6x man7x man8x man9x [root@localhost ~]# ls /usr/share/man ca es it man1 man2x man4 man6 man8 mann pt_BR sv zh_TW cs fr ja man1p man3 man4x man6x man8x nl ru tr da hu ko man1x man3p man5 man7 man9 pl sk uk de id man0p man2 man3x man5x man7x man9x pt sr zh_CN
Running the man page command when man pages are available works as you expect.
[root#localhost !]# man date [root@localhost ~]# DATE(1) User Commands DATE(1) NAME date - print or set the system date and time SYNOPSIS date [OPTION]... [+FORMAT] date [-u|—utc|—universal] [MMDDhhmm[[CC]YY][.ss]] DESCRIPTION Display the current time in the given FORMAT, or set the system date. Mandatory arguments to long options are mandatory for short options too.
When asking about the IP address of the system I was using, I saw the loopback interface (127.0.0.1) and the internal 10.xxx address.
localhost:~$ ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNO WN qlen 1000 link/ether 02:46:81:31:ca:a3 brd ff:ff:ff:ff:ff:ff inet 10.5.218.60/16 brd 10.5.255.255 scope global dynamic eth0 valid_lft 817sec preferred_lft 667sec
Note: When you open a JSLinux console, it will always start from the same place—a fresh Linux terminal. Any texts or changes you make in any way will not be preserved.
Copy.sh is another virtual tool that allows you to run Linux (or a number of other operating systems) inside a browser. To see all available options, go to http://copy.sh/v86/. You’ll find a few dozen options that include Windows, FreeBSD, Oberon, and a number of others in addition to Linux.
I looked at these options:
The Damn Small Linux option provides a graphical interface that I haven’t fully explored yet.
Again, how my script would run varied with the distro I was using. I had to get my script source on Root building The station, but not on Archylinx One.
~% cat showme #!/bin/bash echo “Hi, there” echo -n “What are you looking for?: “ read ans echo “Sorry, I have never heard of coffee” ~% .showme ./showme: not found ~% . ./showme Hi, there What are you looking for?: coffee Sorry, I have never heard of coffee
I also ran Number_command script
~% . ./count_commands
One of the things I liked the most copy.sh Is that it gave me the option to Save Status and Load Status. This means that I was able to preserve the scripts I added and restore them on the next connection from v86state.bin The file that is saved on my system.
The only weird problem I’ve had with copy.sh Stations involving the need to use Control-Alt + Delete Followed by hitting “Cancel” to free my trackball from the clutches of the device.
The speed in Terminal-in-a-browser options isn’t always impressive, but it’s a good idea to try Linux in-browser and explore what it can do for you. There are a lot of Linux commands available, and despite some quirks and performance issues, Linux virtual systems can be very nice to use.
